We are seeking a highly motivated Senior Research Associate to join the Non-Viral Delivery team to support the development of next-generation targeted lipid nanoparticle (tLNP) systems for nucleic acid therapeutics.

In this role, you will contribute to the design, execution, and optimization of formulation strategies to enable efficient and selective delivery to defined cell types. You will take on increased ownership of experimental workflows, generate high-quality datasets to guide program decisions, and collaborate closely with cross-functional teams spanning biology, analytical development, and process sciences.

This hands-on, laboratory-based role is ideal for a scientist who thrives in a fast-paced, highly collaborative environment and is excited to contribute to both program advancement and platform innovation.

Key Responsibilities

Formulation Development & Optimization

• Develop and optimize targeted lipid nanoparticle formulations for delivery of nucleic acid cargos

• Evaluate formulation parameters influencing delivery performance, including composition, ligand density, and process parameters.

• Support the generation of lipid nanoparticles for in vitro and in vivo studies, ensuring consistency, quality, and reproducibility.

• Perform physicochemical, biophysical, and functional characterization of LNPs and conjugates using analytical techniques such as particle sizing (DLS), zeta potential, UV-Vis and fluorescence spectroscopy, and chromatographic or electrophoretic methods (e.g., HPLC, SDS-PAGE, LC/MS)

• Analyze, interpret, and effectively communicate experimental findings through presentations, written reports, and active engagement in scientific discussions and team meetings

• Partner closely with teams in biology, immunology, analytical development, and process development to advance programs.

• Maintain accurate and detailed experimental records while contributing to the improvement of laboratory workflows, robustness, and throughput of formulation and characterization processes.

Required Qualifications

• B.S. or M.S. in Chemical Engineering, Bioengineering, Pharmaceutical Sciences, Chemistry, Biochemistry, or a related field.

• Typically 2–5+ years of relevant experience in an industry or applied research setting.

• Demonstrated hands-on experience with design, synthesis, and characterization of nanoparticle formulations in an industry environment is required.  

• Familiarity with targeted delivery approaches, including ligand conjugation and nanoparticle surface functionalization strategies.

• Proficiency in formulation characterization techniques, including dynamic light scattering, zeta potential, UV-Vis and fluorescence spectroscopy, and chromatographic methods.

• Strong understanding of experimental design and ability to troubleshoot and optimize workflows.

• Exposure to statistical design of experiments (DoE) and data analysis tools.

• Demonstrated ability to work both independently and collaboratively in a team environment.

• Strong organizational skills and attention to detail in data recording and execution.

If you come across a role that intrigues you but doesn’t perfectly line up with your resume, we encourage you to apply anyway. You could be one step away from work that will transform your life and career.
